Ophthalmoplegia, or upper eyelid edema, is a mild elevation of the skin around the eye, with a prominent swollen appearance and with or without pain. The upper eyelid is histologically divided into five layers, with the upper eyelid skin and subcutaneous tissue being one of the weakest and most lax tissues in the body, making it the most susceptible area when irritated by inflammation or when edema occurs in the body. Upper eyelid edema often occurs in people with poor circulation and metabolism, such as those who habitually drink a lot of water before bed, those who sleep in an improper position, those who have a low pillow, those who are sedentary, those who have a heavy and salty diet, and those who stay up all night, etc. As a result, the blood circulation system is poor and it is too late to remove excess water from the body. Puffiness. In addition, some pathological factors can cause eyelid edema, such as acute and chronic nephritis, decreased kidney function, heart disease, functional thyroid disease, and endocrine disorders. Eyelid disorders such as blepharitis, eyelid allergies, inflammation of the conjunctiva, inflammation of the lacrimal apparatus, or some occupational lesions of the orbit, and infectious conditions such as orbital cellulitis can lead to upper lid edema. Thyroid-related eye disease can also cause eyelid edema, so it is important to have eyelid edema examined and treated at a regular hospital ophthalmology clinic.
